Answer:

Option 2.

Step-by-step explanation:

The antifreeze claims to protect between -30 C and 130 C. The inequality should be this: $-30$

You can replace C with the Fahrenheit formula: C= $\frac{5}{9} (F-32)$

So, the inequality becomes $-30$

Find the area to the nearest square foot of the shaded region below, consisting of a square with a circle cut out of it. Use

Simora [160]

Answer:

the area is 10 feet by 10 feet, 100 feet²

subtract the area of the circle from this.

you get it by A = r² * pi

so 5² * 3.14159...

=78.5398163397

100-78.5398163397

is roughly 21.46 square feet

Identify the zeros of the polynomial function N(x)=1/2 (x-1)(x+3).

zhannawk [14.2K]

Answer:

a:x=-3

c:x=1

Step-by-step explanation:

The zeros of a function are the values of x for which the value of the function f(x) becomes zero.

In this problem, we have the following function:

$f(x)=\frac{1}{2}(x-1)(x+3)$

Here we want to find the zeros of the function, i.e. the values of x for which

$f(x)=0$

In order to make f(x) equal to zero, either one of the factors $(x-1)$ or $(x+3)$ must be equal to zero.

Therefore, the two zeros can be found by requiring that:

$x-1=0\\\rightarrow x=+1$

$x+3=0\\\rightarrow x=-3$

So the correct options are

a:x=-3

c:x=1
